Ticket #3713 (closed defect: fixed)
Linked Data causes ~25% overhead/DB explosion
|Reported by:||tdb01r||Owned by:||cjg|
|Priority:||Must do||Milestone:||EPrints 3.2.1|
The rdf field (when populated) adds ~58 values per record, corresponding to ~300 DB rows.
- any dependent field requires re-writing the entire rdf field (300 rows+)
- requesting an eprint reads all rows
In testing this adds ~25% overhead on all EPrints retrieval-based operations.
For a medium-sized repository (10k records) the rdf tables will be 500k rows long. This is not scalable for a core field.
